90 / 102 page Numonyx™ Wireless Flash Memory (W18) Datasheet November 2007 90 Order Number: 290701-18 Numonyx™ Wireless Flash Memory (W18) B.2 Query Structure Overview The Query command causes the flash component to display the Common Flash Interface (CFI) Query structure or “database.” The structure sub-sections and address locations are summarized below. Table 38: Query Structure Notes: 1. Refer to the Query Structure Output section and offset 28h for the detailed definition of offset address as a function of device bus width and mode. 2. BA = Block Address beginning location (i.e., 08000h is block 1’s beginning location when the block size is 32K-word). 3. Offset 15 defines “P” which points to the Primary Numonyx-specific Extended Query Table. B.3 Block Status Register The Block Status Register indicates whether an erase operation completed successfully or whether a given block is locked or can be accessed for flash program/erase operations. Block Erase Status (BSR.1) allows system software to determine the success of the last block erase operation. BSR.1 can be used just after power-up to verify that the VCC supply was not accidentally removed during an erase operation.
